Abstract

Production of aflatoxins was conducted using an identified toxin-producing strain of Aspergillus flavus and both natural (rice and corn) and semisynthetic (YES) media. Qualitative data showed that the strain of A. flavus was capable to produce four types of aflatoxins, namely By, Bz, G, and G92 on rice, corn and YES media. Quantitative data showed that the concentrations of aflatoxins B) and G) produced were much higher, being 52, 40.3.& 34.6 and 64.7, 45.0 & 28.9 ug for 50 gm of rice, corn and YES media, respectively, while, the yielded amounts of aflatoxins Bz and Go were 11.5, 17.9 & 17.5 and 28.9, 40.3 & 39.5 ug for 50 gm of rice, corn and YES media, respectively.
